Not a particular fan of picture of this style( as in car and cycle pictures) but The first picture is just awesome in my opinion, the reflections are nice and the background is awesome.
Looks like straight out of a mag!
(also, im liking the bikes color =D)

First shot is definitely the best because the huge depth of field works for it... the other ones are weaker because of the composition but also the huge amount that is in focus. If you could recreate the type of shot you see in your first image every time you're onto something... Nice stuff!
